You might have heard that the lines on your palm can reveal things about your personality and future. But what if your palm had something different from most people? Instead of having two separate lines — one for thinking (head line) and one for feeling (heart line) — there’s just one single line running straight across your palm. This is called the Simian Line (simian crease).
Also known as the transverse palmar crease, simian crease, or in colloquial terms, the monkey line, is a rare and fascinating line in palmistry. In Hindi, it’s referred to as “Kapi Rekha”—a name inspired by its similarity to the hand lines found in monkeys. If you closely observe a monkey’s hand, you’ll notice a straight line across the palm, which is where the name originates.
Unlike the usual palm structure, which displays a separate heart line and head line, the simian line merges both into a single horizontal straight line across palm. This physical and symbolic union of heart and mind is believed to influence one’s personality, destiny, and sometimes, even health.
Simian Line Meaning
The simian line is a straight line across palm that replaces the normal two-line configuration of the heart and head lines. Found in less than 5% of the population, it’s often considered a mark of intensity, focus, and inner conflict. It is important to note that this line is neither purely positive nor negative — it reflects extremes and concentrated energy.
Palmists associate this simian crease with individuals who either achieve great success through their laser focus or face deep emotional and mental turmoil due to internal confusion. The dual nature of this line makes it one of the most intriguing features in palmistry.
Simian Line Personality Traits
People with a simian crease (simian line) often exhibit polarized personality traits, depending on how well they integrate their emotional and intellectual sides.

Simian Line Remedy: How to Balance it’s Effects
According to MyRatna’s experienced palmists, people who have a Simian Line often show strong emotional and mental energy that can sometimes feel overwhelming or out of balance. To help manage this intensity, one of the most effective astrological remedies suggested is wearing a Blue Sapphire (Neelam) Stone. This gemstone is linked to the planet Saturn (Shani), which brings calmness, focus, and emotional stability. However, since original neelam stone is a very powerful stone, it should only be worn after proper astrological guidance to make sure it suits your palm/birth chart.
Why Blue Sapphire (Neelam Stone)?
Associated with Shani (Saturn), the planet of discipline, structure, and karma.
Helps in calming obsessive thoughts, grounding emotional turbulence.
Promotes mental clarity, patience, and detachment — exactly what’s needed to balance the simian line traits.
You can wear the Blue Sapphire stone in a ring or pendant, depending on personal comfort and astrological guidance.
